Question

Two sides of a triangle measure 8 cm and 15 cm. Which could be the length of the third side

Plz help

Answer 1

From the choices 6, 18, 24, 28. It’s 18

Explanation:

The sum of any 2 sides of the triangle should be greater than the third side.

8+15= 23

That excludes choices 24 and 28.

Supposing it’s 6, try the same rule again

6 + 8 = 14 it isn’t greater than 15

Which means the answer is 18

Hope this helps
